A cookie recipe calls for 2-3/4 cups of flour and 1-1/4 cups of sugar. If the amount of the ingredients are increased proportionally, and the amount of sugar is increased to 10 cups, how many cups of flour would be needed?
1.25/2.75 = 10/x
Cross multiply and solve for x.

To find out how many cups of flour would be needed when the amount of sugar is increased to 10 cups, we need to determine the ratio between the amount of sugar and the amount of flour in the original recipe.
In the original recipe, the ratio of sugar to flour is 1-1/4 cups of sugar to 2-3/4 cups of flour.
To increase the amount of sugar to 10 cups, we need to scale up the original ratio by multiplying it by a factor that equates the old sugar value to the new sugar value.
10 cups of sugar / 1-1/4 cups of sugar = 10 / (5/4) = 10 * (4/5) = 8 cups.
So, if the amount of sugar is increased to 10 cups, we would need 8 cups of flour to maintain the same ratio between the two ingredients.
